With fpecimens of both the infefts figured by Edwards and Cramer before us, we cannot hefitate to
confider them Sphinges o f the Adfcita^ family, and o f the Zygesna o f Fabricius. In removing our infect
to the fphinx genus, we have retained the fpecific name Thallo, as more likely to denote the fpecies than
any newly adopted name. The infeft figured by Cramer does not precifely agree with Edwards's figure.
In the firft, the dilk o f the pofterior wings are yellowifli, with a deep border of black: in the other, the
yellow occupies only a fpace near the bafe, and forms a femi-kuiar mark near the anterior margin o f thofe
wings. We fufpeft, with Cramer, that they are but the two fexes of one fpecies. Cramer fays both his
fpecimens came from China, from whence our infefts were alfo received.

This and the following fpecies are undoubted nondefcripts: both fpecimens are in the colleftion of
Mr. Francillon, who received them from China.

Sphinx Hylas, Thallo, ruficollis, and the elegant little fpecies Sphinx bifafciata, are reprefented on the
plate with the
T h u ja O rien ialis.— China Ahor-vit¿e Tree,
An ornamental evergreen, much efteemed by the Chinefe, and very frequently reprefented in their laud-
fcapes. Sir G. Staunton remarks in the account of the journey from Pekin to Canton, that great quantities
of this plant grew to a prodigious height in the valley in which ftands the city of Yen-choo-foo.
g The Adfcitse differ from the other fjihinges, in their general appearance, but have all the charafters affigned to that genus.
